Understanding The Toilet Cistern Parts Is Vital To Detecting And Fixing Common Toilet Issues

The toilet cistern is a separate piece attached to the bowl upon installation. It collects water from the home’s water source. The tank sends all of that water rushing into the bowl upon demand. It will flush all the waste materials into the sewer. Toilet cisterns have many moving parts that wear out or break over time. You can try & fix or replacing these vital toilet cistern parts if your toilet won’t stop running. Understanding the toilet cistern parts is helpful to diagnose and fix common toilet issues. A few of them are as follows:


Toilet Bowl: 

The large base on which the user sits in the toilet bowl. Most toilet bowls are waterproof material that resists stains well and has an oblong or round hole to take waste. A C-shaped internal trap in the bowl collects garbage and transports it away. The trap also serves as a seal against sewer gases escaping into the house by retaining a small freshwater supply.

Tank O-Ring Seal:

A tank o-ring seal, mack washer, or tank-to-bowl gasket is a large O-shaped rubber or washer or gasket that fits between the bottom of the toilet tank and the top of the toilet bowl. Its function is to keep water from leaking from the toilet tank. Unfortunately, a poorly installed or fractured O-ring seal is frequently the cause of a toilet leaking below the tank but above the bowl. The answer is to drain the water from the tank, remove it, and replace the O-ring with a new one.


Floor Flange:

A floor flange is a spherical metal or plastic bracket that sits above and below the toilet bowl, projecting from the floor. It is firmly attached to the base by screws or bolts. The toilet connects to the flange with T-bolts. However, it may rust and break, leaving the toilet shaky and prone to leaks. Therefore, the toilet must be removed, the flange must be removed and replaced, and the toilet must be reinstalled.

Wax Seal:

A wax seal is placed around a cone-shaped gasket that fits the toilet bowl’s bottom and the floor flange’s top. It aims to keep toilet water from spilling out. Wax seals can only be used once. The wax seal on a toilet that leaks at the base could be cracked or insufficiently sized for the space. Remove the scrape off the old wax ring, throw it away, and replace it with a new wax ring or silicone ring.


Toilet Tank:

The toilet tank is the upper back part of the toilet, which rests on the top of the toilet bowl. It is made of porcelain & they rarely malfunction. But it may crack or break. However, it is repairable by applying silicone plumbing epoxy to the crack.


The handle in a toilet is the lever located on the toilet tank used to flush the toilet. In some cases, it may be a large button on the top of the toilet lid. Dual flush toilets have two buttons where one is used for flushing liquid waste and another is used for flushing solid waste. Its malfunction is rare. However, it can be replaced easily.



The toilet flapper is a rubber stopper that lifts and closes to deliver water into the toilet bowl. It is placed on the inside base of the toilet tank. The toilet handle or lever controls the toilet flapper through a chain. Like a rubber stopper in a bathtub, the flapper returns to its original position after the water has been released and seals the opening at the bottom of the tank.
